Had a few months with this helmet now and have really been pleased with it. Coming off a 2 week trip into the desert mountains in west Texas, I experienced very high winds combined with interstate speeds, heavy dust, temps from 28 to 90 and have nothing to complain about - lovin it.
As mentioned before I think the noise is about the same as XD and I think the venting might be less. Only gripe has been I can't mount my GoPro on it as easily LOL
Will probably order another and a couple of spare shields in case they don't bring them over here
